Here is an example I found with 19x8.5 with the stock tires which are 225/55/19 and many angles. There's little to no stretch. The page takes awhile to load and sometimes needs to be refreshed because it has a lot of pics...
I went with the Eibach Pro kit and had an alignment done as well. Everything went back into spec and it drives like it's on rails. Really fun to drive.
Picked up a 2019 Signature a few weeks back and replaced the wheels with RAYS Gram Lights 57Transcend. Specs are 19x8.5" 38mm offset, tires 245/50/19. Perfect flush with fenders lowered with the Eibach pro kit springs.
